Roasted cauliflower? Been there, done that. But roasting a whole head of cauliflower? Now we’ve got your attention. This recipe has you slathering cauliflower in a spicy yogurt marinade and roasting it at a high temperature. The result is an amazingly delicious dish that’s as dramatic in presentation as it is easy in preparation. Serve it with a big green salad (we suggest lime juice and olive oil for the dressing) for an easy weeknight supper or your next “the vegetarians are coming to dinner” party.
